Master Bond EP30-2LB blocks UV light from 200-400 nm and allows the transmission of visible light from 450-900 nm. This two part system is optically clear with a refractive index of 1.55. It also passes ASTM E595 testing to meet NASA low outgassing specifications.
Beyond its optical properties, EP30-2LB is a reliable structural adhesive with a tensile lap shear strength of 3,000-3,200 psi and a compressive strength of 14,000-15,000 psi. It bonds well to a wide variety of substrates including metals, composites, glass, ceramics, rubbers and plastics. This epoxy has a ten to one mix ratio by weight and flows smoothly and evenly, enabling it to be used for coating, sealing and encapsulation applications. It is a capable electrical insulator, is dimensionally stable and has low shrinkage upon cure. This material also is easily machineable.
EP30-2LB resists chemicals including water, oils, fuels, acids and bases and many solvents. It is serviceable from -80°F to +300°F [-62°C to +149°C]. This compound has a shelf life of one year at room temperature in its original, unopened containers. It is available for use in ½ pint, pint, quart, gallon and 5 gallon container kits as well as gun dispensers.
